The SARL-S (Société à Responsabilité Limitée Simplifiée) is a streamlined version of the classic SARL, designed by Luxembourg’s legislature to lower the barrier to entrepreneurship. Its main appeal lies in a minimum share capital of just €1, combined with a simplified incorporation procedure that does not require a notarial deed.
Originally introduced to encourage business creation in low-capital service sectors, the SARL-S shares the fundamental advantages of the classic SARL: shareholder liability limited to contributions, standard taxation under corporate income tax (CIT), municipal business tax (MBT) and net wealth tax (NWT). It therefore offers full legal protection without any financial barrier to entry.
In return for this accessibility, the legislature has imposed strict restrictions. Capital is capped at €11,999, certain activities — finance, holding companies, insurance — are formally prohibited, and the manager must be a natural person. The SARL-S is therefore a stepping stone to entrepreneurship, not a long-term growth structure: as soon as the project scales, conversion to a classic SARL becomes necessary.
This guide sets out the legal framework, practical advantages, limitations to anticipate and the steps involved in converting to a standard SARL. For a broader comparison of available legal forms, see the company formation page and the guides on the SA and SAS.
Legal characteristics of the SARL-S
Share capital and payment
The share capital of a SARL-S ranges from €1 to €11,999 and must be fully subscribed at incorporation. Since the Law of 18 May 2026 amending the amended Law of 10 August 1915 on commercial companies, payment of cash contributions may be deferred for up to twelve months where the incorporation deed sets the terms. The reform also permits contributions in kind to a SARL-S, but they must be fully paid at incorporation. Deferral can therefore cover the entire subscribed capital only where that capital is contributed in cash.
| Criterion | SARL-S | Classic SARL |
|---|---|---|
| Minimum capital | €1 | €12,000 |
| Maximum capital | €11,999 | Unlimited |
| Subscription | 100 % at incorporation | 100 % at incorporation |
| Payment | Cash deferrable up to 12 months (articles) | Cash deferrable up to 12 months (articles) |
| Contributions in kind | Permitted; fully paid at incorporation | Permitted; fully paid at incorporation |
In practice, deferred payment is of limited use for a SARL-S whose capital is only a few euros; it becomes meaningful as the capital approaches the €11,999 ceiling.
Shareholders and management
The SARL-S may have between 1 and 100 shareholders, identical to the classic SARL. However, one key restriction sets it apart: the manager must be a natural person. It is therefore impossible to appoint a holding company as manager, which rules out the SARL-S for group structuring schemes involving a SOPARFI.
Formation without a notary
A SARL-S can be formed by private deed (without a notary), using model articles of association provided by the Trade and Companies Register (RCS). This simplification reduces both timelines and launch costs.
The absence of a notary does not exempt the company from RCS registration or publication in the RESA. These formalities remain mandatory.
Practical advantages of the SARL-S
The SARL-S is ideally suited to low-investment service projects:
| Advantage | Detail | Typical profile |
|---|---|---|
| Capital from €1 | No financial barrier to entry | Freelancers, consultants, coaches |
| No notarial deed | Model articles, accelerated procedure | Quick launch, market testing |
| Low formation costs | Save €1,500–3,000 in notary fees | Micro-businesses, solo activities |
| Limited liability | Personal assets protected, same as SARL | All entrepreneurs |
| Same tax treatment as SARL | CIT, MBT, NWT — no special regime | Activities subject to corporate tax |
A communications consultant can incorporate a SARL-S with €100 of capital, start trading within days and test the market without tying up cash. If the activity grows and requires investment, conversion to a classic SARL can follow later.
Limits and restrictions
The capital cap at €11,999
The SARL-S may under no circumstances exceed a capital of €11,999. As soon as the company’s needs — investments, hiring, working capital — outgrow this ceiling, conversion to a classic SARL is mandatory, requiring a notarial deed and a capital increase to at least €12,000.
Prohibited activities
The legislature formally excludes the SARL-S from the following sectors:
| Prohibited sector | Required legal form |
|---|---|
| Financial services, asset management | SARL, SA |
| Stock-exchange operations (incl. crypto-assets) | SA, SARL |
| Financial holding companies (SOPARFI) | SA, SARL |
| Insurance, reinsurance, brokerage | SA |
| Investment funds | SA, SAS |
| Pure holding | SA, SARL |
These restrictions reflect the legislator’s intention to reserve the SARL-S for genuine service activities, preventing its use as a financial vehicle with a token capital.
The reinforced legal reserve
Each financial year, the SARL-S must allocate 5 % of its net profit to a legal reserve fund. This obligation continues until the reserve reaches €12,000 — the minimum capital of a classic SARL. During this period, the company’s dividend distribution capacity is mechanically reduced.
Once the €12,000 reserve is constituted, the SARL-S must be converted into a classic SARL. This mechanism makes the SARL-S a temporary legal form by design.
Banking and commercial credibility
A share capital of a few euros can hinder relations with third parties:
- Banks may be reluctant to open a business account or grant financing
- Certain suppliers or institutional clients may require a higher minimum capital
- Public tenders may impose equity thresholds
The business permit
The SARL-S does not exempt the entrepreneur from obtaining a business permit (autorisation d’établissement). If the intended activity is commercial, artisanal or a regulated profession, this permit must be obtained from the Ministry of the Economy before RCS registration. The manager’s professional qualifications are verified in the same way as for any other legal form. The article on the Luxembourg business permit sets out the permit holder logic, the integrity test and the premises requirement in full.
If the SARL-S’s corporate purpose does not fall within an activity subject to the right of establishment, the SARL-S form is prohibited. The SARL-S is reserved for activities requiring a business permit.
The formation process
| Step | Indicative timeframe | Detail |
|---|---|---|
| Drafting the articles (RCS model) | 1–3 days | Private deed, no notary required |
| Bank KYC and account opening | Variable | May run in parallel where cash capital is paid after incorporation |
| RCS registration | 2–5 days | Filing of the complete dossier |
| RESA publication | Automatic | Handled by the RCS |
| Business permit | Variable | Mandatory depending on the activity |
| VAT identification (AED) | 1–2 weeks | If the activity is subject to VAT |
With immediate cash payment, the funds are paid at incorporation. Where the incorporation deed provides for deferred payment, the capital must be paid under that schedule and no later than twelve months after incorporation.
Indicative total cost: €200–500 (excluding share capital) — a significant saving compared to the classic SARL (€2,500–5,000 including notary fees). The full company formation process can be handled end to end.
When to convert the SARL-S into a classic SARL
Conversion is a natural growth step. It becomes necessary in the following situations:
| Trigger | Explanation |
|---|---|
| Legal reserve reaches €12,000 | Mandatory conversion required by law |
| Capital needs exceed €12,000 | Financing investments, hiring or working capital |
| Seeking investors | Providing a credible structure with meaningful capital |
| Financial or holding activity | Sectors prohibited for the SARL-S |
| Appointing a legal-entity manager | Group structuring impossible under SARL-S |
| Banking difficulties | Strengthening credibility with financial institutions |
The conversion is carried out by notarial deed, with a capital increase to at least €12,000. The total cost (notary fees + RCS charges) typically ranges from €1,500 to €2,500. A precise estimate can be obtained through dedicated company formation support.
Accounting and tax obligations
The SARL-S is subject to the same obligations as the classic SARL:
| Obligation | Deadline |
|---|---|
| Maintain proper accounting records | Ongoing |
| File annual accounts with the RCS | Within one month of the AGM |
| Tax returns (CIT, MBT, NWT) | 31 May of year N+1 |
| Allocate 5 % of net profit to the legal reserve | Each financial year |
| VAT returns | Quarterly or monthly |
| Payroll management | If employees are hired |
Manager remuneration and any benefits in kind (company car, housing) follow the same tax rules as for a classic SARL. A domiciliation address is required throughout the company’s existence.

Explore company formation supportFrequently Asked Questions
Can you create a SARL-S with €1 of capital?
Yes. The legal minimum capital is €1. In practice, it is advisable to provide enough capital to cover the first months of activity (domiciliation, accounting, insurance), typically between €100 and €500.
Can the SARL-S hire employees?
Yes, with no restriction on numbers. The company must register with the Joint Social Security Centre (CCSS) and comply with Luxembourg labour law. Payroll management can be outsourced to a specialist provider.
How long does it take to create a SARL-S?
The bank account is no longer a systematic pre-incorporation step. Where the incorporation deed provides for deferred payment of cash capital, the SARL-S can be incorporated and registered without waiting for an account or blocking certificate. Timing then depends mainly on document preparation, the business permit required before RCS registration and RCS processing. Bank KYC can continue in parallel.
Can a non-resident create a SARL-S?
Yes, provided they meet the professional qualification requirements for the business permit and can provide a registered address (domiciliation) in Luxembourg.
How do you convert a SARL-S into a classic SARL?
The conversion requires a notarial deed increasing capital to at least €12,000, amending the articles and publishing in the RESA. The operation typically costs between €1,500 and €2,500 (notary fees + administrative costs).
